What are the best ways to get unbiased opinions about a school?
I don't know that you truly can for everyone has their own biases and their own values and anything they share, however sincere, reflects, at least in part, that fact. Schools seek to present a particular message based on their needs and what they are seeking in a student body and evey alum or current student is offering opinions and information viewed through their personal lens. Statstics can be somewhat objective but what they measure is only a fraction of the whole picture. Education is a tremendously human process and no amount of study or research can give you a definitive answer about how it will resonate with another individual. You can--and should--try to get as much information as you can, but in the end it will come down to how the process and the experience connects with you
